DOOR-STOP.

SPECIFICATION forming part of Letters Patent No. 7 52,171, dated. February 16, 1904. I

Application filed December 22, 1902. Serial No. 136,156. (No model.)

To all whom it may concern:

Be it known that we, OSWALD Looxnr'r, MIoHEAL J. KENNY, JOHN I. STIMEBACH, and

. THEODORE H. UDELL, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Door- Stops, of which the following is a full, clear, and exact specification.

Our invention relates to that class of doorstops more especially designed for holding self-closing doors wholly or partially open; and it has for its primary object to provide an improved form of door-stop which will not interfere with the movement of the door in either direction when the door is opened and closed in the ordinary way, but which will prevent the closing of the door if the door he opened to a certain extent and then released.

With these ends in view our invention con sists in certain novel features in the construction, combination, and arrangement of parts by which the said objects and certain other ob jects hereinafter appearing are attained, all as fully described, with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a side ele vation of our improved door-stop, showing the door closed. Fig. 2 is a similar view showing the door open with the stop in engagement, and Fig. 3 is a plan view on a small scale.

1 is a bracket or horizontally-projecting arm which is adapted to be secured to the door jamb or frame or some other part fixed with relation to the door 2, and formed on or secured to the outer end of this arm or bracket 1 is a notched portion 3, which is in the form of an upwardly extending or inclined flange and which has pivotally supported at its upper end a swinging lip or guard 4:, which is of suflicient size to entirely cover the notch 3 when pushed inwardly. Secured to the door 2 is another bracket or arm 5, in the outerend of which is pivoted a pawl 6, provided with a weight 7 or other suitable means for holding the upper end of thepawl normally above or at least on a level with the notch3, the downward movementof the weight and the upward movement of the pawl beinglimited by a stop 8, formed on the bracket 5.

When the door is allowed to close in the ordinary way, the point of the pawl engages the outer plain face of the lip or shield 4: and forces the lip inwardly until the lip rests against and completely covers the notch 3, and thereby forms a smooth surface downwardly inclined or beveled for the point of the pawl 6 to rub against during the closing movement, and consequently the pawl does not engage the notch 3 and the door is allowed to close. When the door is opened in the ordinary'way, the upper end of the pawl, which is inclined toward the door, drags freely under the outer end of the bracket or arm 1 and the lip I, deflecting the latter outwardly, and thus passes without interference, no matter how rapidly or violently the door may be opened or closed. Shouldit be desired, however, to cause the point of the pawl to engage the notch 3 and hold the door ajar, the door will be opened gradually until the pawl engages under and lifts the lip 4:, and if now the door be released 'or allowed to partially close the point of the pawl will engage the notch 3 and hold the door open until the door is again pushed outwardly or opened to an extent carrying the point of the pawl away from the lip 4, so as to allow the latter to descend between the point of the pawl and the notch 3.

It is of course understood that the extent to which the door may be held ajar or wholly or partially opened depends not only upon the length of the arm 1, but uponthe position of this arm with relation to the hinges of the door.

Having thus described our invention, what we claim as new therein, and desire to secure by Letters Patent, is

1. In a door-stop the combination with the door and the door-jamb or part fixed with relation to the door, of a pivoted pawl attached to one of said parts, a member with which said pawl engages attached to the other of said parts and a deflectable shield hanging nor:

mally in the line of movement of the end of said pawl and shielding said member from gngzilgement by said pawl, substantially as set ort door and the door-jamb or part fixed with relation to the door, of a pivoted pawl secured to one of said members and a pawl-arresting member secured to the other and adapted to be engaged by said pawl, and a swinging lip. arranged in the line of movement of said pawl and adapted to cover said pawl arresting member, substantially as, setforth,

3. In a door-stop the combination with the v door or door-jamb or part fixed with relation to the door, of a pawl pivoted to one of said parts and an arm secured to the other and projecting horizontally, the outer end of said arm having a notch for the engagement of said pawl and an upwardly-inclined flange projecting away from said arm, and a shield on lip hinged to said flange and depending in the line of movement of said pawl, substantially as set forth.

4. Ina door-stop the combination with the door and the door-jamb or part, fixed with re- 2. In adoor-stop the combination with the lation to the door, of a pivotedipawl secured to a one of said parts, means. for holding the point of said pawl elevated, a stop for limiting the movement of said pawl, a notched member secured to the other one of said parts and ar- A ranged to be engaged by said pawl, and means for shielding said notch from engagement by said pawl, substantially as set forth.
